IMPROVEMENT IN MACHINES FOR MAKING METALLIC SPOOLS.

I 'Specilieatiou forming part of Letters Patent No. 210,088, datedNovember 19, 1878; application filed' To all whom it/)nay concern:

Be it known tha-tl, LATHAM BRIGHTMAN, of Cleveland, county of Cuyahoga.,State of Ohio, have invented or discovered a new and useful Improvementin Metallic -Spools and their Mamifacture; and I do-hereb'y decla-re thevfollowing to he a full, clear, concise, and

'v exact description thereofreterence being had to the accompanyingdrawing, makiijig a part of this spccilieation, in whieh-likelettersindicating like parts- Y 1 Figure l isA a perspective view of my im-Aproved machine for making metallic spools. Fig. 2 1s a top-plan view ofthe same drawn to ,a reduced scale. Figs. 3 and 4 are detached p la-nviews, drawn to a scale larger than Fig.

l, showing more fullythe operation ofthe machine upon the spool. Figs.5, 6, 7, and S arev enlarged detached views of parts of the spool,illustrative of steps in its manufacture; and Fig. f) is a perspectiveview of a spool as made `on my'improved machine.

vIn preparing wire for use on self-binding harvesters it has been foundconvenient to wind such wires in continuous 'lines upon spools ofsuitable construction, such spools beingarranged on the binding deviceof the harvester in such way that the wire may be unwound therefrom asrequired.

My present improvement relates to the machine forthe manufacture ofmetallic spools suitable for this purpose.

In the drawings, H, Fig. 5, represents a sheet-metal plate or blank.shcared orstamped t0 ,the proper form and size for formingthe` shaft orbarrel H of the spool. I prefer to punch one or more small holes, h, inthis blank II, i'n which the end of the wire may be fastened preparatoryto winding the spool. l I also clip'the corners hl a little, and, ifdesired,

- notches 71.2 may be cnt from the edges forming the ends of the barrelH', sothat the blank being .bent `to cylindrical form, as in Fig. 8,

the ends of such cylinder or barrel may be tapered somewhat, as at l.

The disks or heads of the spool K are cut circular, by preference, andone or more small holes, le', made in one-or both disks for fastening"the vend of the wire.' Central holes 7c are also made, having, bypreference, 'a diam'- eter a little less than the full diameter of theAugust 26, 1878,

barrel HI', but large enough to allow the disks K to be slipped onto thetapered ends of the barrel, with the ends of thetapers l protrudingsomewhat. The holes k' may, however, he,

made large enough to allow the disks to more onto the full size of theba'rrel; but I prefer to have them t tightly thereon, so as to keep-.their places. These disks K are secured on the barrel H' by'bendiug orflan ging the protruding ends l of the barrel against the outer faces ofthe disks, as seen in Fig-9.

I make use of the following-descrbed appa-1 I ratus for performing thislast-mentioned fla-nging operation: In the drawing, A 'represents the maln frame or bed-plate,- which may bc supported in any suit-ableway. Onthe opposite ends of .this frame are 1nounted,in suitable bcarin gs,shaft-s a, a', which are driven bythe spur-gear wheels B B andcrank-pinion b'. Other suitable driving mechanism may, however, beemployed sets or puneh'esare actuated by the shaftsa-a y I on theirrespective sides as folloivsz- Frein each of thel blocks c c' two guideor slide bars,

d d d' d', extend back to or 'against wipersor eceen'trics 'it z" i on`their respect-ive shafts a a'. In thus extending back these guides 'orbars d d pass through suitably-shaped boxes or bearingsv in the crossblocks or beams m, so that while the bars d d' andblocks e c are kept inplace, they are yetfree to 4mov-'e longi-` tudinally in such` bearings,and when the.

wipers 'i i press Aagainst; the adjacent ends of the guide-bars d d theblocks e ev will be carried forward or toward each other. -In order to`carry theseblocks backward again, I arrange 'levers or swinging bars ggl outside of. 4the shafts aa', and adjacent t0 or so as to be operatedbyv thewipers i'. `Thcsfe 'levers arel pivoted at thei1` lower ends tocross-rods '(12, andat their upper ends they are connected y rods y y'to vposts ff', which extend up from theblocks ,c e'. As the wipers t' z"are turned to the outside of their respective 'shafts they will pfressArespectively against the levers g gl, lnovingfor swinging'them outward,and

Vthereby''drawing the blocks e c' back orawayfrom each "otler.

The sets or punches u 'n' are made slightly tapering toward the point,and with .Shoalders 'c o' at or near the base of each, so that i thepoints of `thepunches may enter the tapered ends of the barrel H' andopen them out,

' i while the shoulders ce' will flange or bend such ends against theoutside of the disks K.

These punches or sets are, arranged to operate througlropenings in theblocks ec', They are carried by'sterns or guidc-barso o, which extendback through suitable bearings` in the.

' beams m to or against-eccentries or wipers r 1" on tlie'shafts a. a.'As' these wipers -press yagainst the adjacent endsof the stems o othe"punches or sets will be carried forward or to- `or sets n n'are drawnback along w-ithl the blocks ce', the blocks engaging' shoulders o2 onthe stems o o'. p Y

An anvil-block, D -D','- for holding the spool to be operated on, isarranged inline between the blocks e e' and 'sets n 'n'. It 'is made intwoparts, as shown, and the parts hinged to.

gether in any 'suitableivayn Ineach of these parts D D', and in linewith the punchesor sets n n', is a concave or haltcylindrical groove,

A u u', in' which the barrel II' of the spool rests.

The lengt-h of this block D D' is equal to the desired length of thespool between thedisk's K.

A hook, j, is pivoted to the part D, and as -rangedto'hook onto a studor pin, j', on the other part, D', and thus hold the two parts together.Springs 'or clips v o are arranged one on each end of the part D', so;that the'disks K may be slipped between them andthe ends' l of theblock, and thus held in place upon the tapered ends l of the barreluntil the blocks e e' advance vand force them on tight, and thefastening operation is completed.

l Prongs vor forks 'w fw aresecured tothe base Aer other convenient`partof the device, and a* -my hand.-

l y, I .2i-01088 BESTAVAILABLE Cop? they are so adjustedas to engage thedisks K when the'part D' is raised or opened up, '(see Fig. 1,) an pushthe spool. out of its seat.

This operation may, however, be performed by h'and or in any convenientWay.

'If spools of dilferent lengths are required, the holding-block D D' maybe removed along with its attached devices, and another substitutedhaving a length equal'to the desired length ofspool; and in order thento ,secure the proper adjustment of pressure-blocks@ c" and sets im',the bars d d' and o o' may be replaced With others of the requisitelength; or they may be lengthened or shortened, as re.

quired, by means of packers or linings and suitable extension-joints, asat d', Fig. 2.

'The operation of this device is as'follows:

The disks K and barrel H' heilig prepared as befre'described, thebarrel'H' is laid in'the groove u,the part D' closed :down and se-'cured, whilethe 'disksare so held on the tapered ends Z as to beclasped between the .clips or springs 'v c and the ends of the block.

The device is then put in motion. The blocks e ve'lare firstcrowdedvagainst the disks Kby the Wipers lii', thus forcing the diskstight' upon the ends of the barrel. vThe sets or punches n. u' thenadvance, and, entering the ends of the barrel, they flange or-bend suchends against the outer faces of the disks' and fasten them in place.'The blocks c c' and punches n n' are then carried back, asbeforedescribed, the upper part, D', of the anvil- `or holding-block is openedup, and the finished spoolremoved ,eitherbythe prongs w uf or in otherconvenient way.

I claim herein as my invention- 1v theeombination of a holdinglblockforjholding' the barrel while 'operated on, pressureblocks .`for forcingthe heads'or. disks ;ot` the spool upon the barrel, and sets or punchesfor hanging the ends ,of the barrel against the disks, substantially asdescribed.
